GI Motitility In the Stomach. 1  Two types of movement (motility) occur in the stomach: peristalsis and segmentation (mixing). 2  The contractions occur about every 20 seconds and proceed from the body of the stomach toward the pyloric sphincter. 3  About 20% of the contractions in the stomach are peristaltic waves.
Peristalsis is a series of muscle contractions and relaxations that occur along the course of the intestinal tract to push food and waste products through.In some cases, people can actually feel the contractions as they occur, especially in the case of movements of the large intestine. cow takes part in 'reverse peristalsis' when its digestive tract pulls cud back into the esophagus so that it can be chewed again. Peristalsis begins with the esophagus. Vomiting is an example of the body overriding the usual muscle movements of peristalsis.
